"Spurgeon is still pretty young, but I’m sure that as he continues to grow, I will find that I tend to do some things differently than my mom did," Jessa, 23, tells Us. "That’s the beauty of the individual family. No one is identical."

"There will be variations with little things here and there, but I know that our foundational goals remain the same — to raise our kids to love God and be a blessing to others," continues the Arkansas-based reality-TV mainstay, who welcomed Spurgeon with husband Ben Seewald in November 2015.

The Jill & Jessa: Counting On star says she's lucky that she has such a valuable resource in mom Michelle — who has 19 children — with Jessa calling her mother a "baby encyclopedia." But the first-time mom is also quick to point out that Michelle encourages her to blaze her own trail.

"Every time I come to my mom for advice, she always reminds me that I’ve got this," Jessa says. "There’s no pressure to do things just exactly how she did them, but I’m so grateful for all her advice and help. Even when I feel overwhelmed, she’s always there to encourage me and tell me, 'You’re doing a great job!' That gives me the courage to trust my instincts and do what I feel is best for my baby."
